Quick overview

  • Two inch size Sized for 2 inch heater unions.
  • Split design The nut comes in two halves that close around the pipe, so the plumbing does not have to be cut apart.
  • Screws included The fasteners that draw the two halves together are supplied with the nut.
  • Made for heater repair Listed specifically as a heater repair part rather than a general plumbing nut.
  • Saves a replumb A cracked union nut normally means cutting pipe, and a split nut avoids that on a tight heater installation.
  • Hand tighten only Union nuts seal on an o-ring, so they are tightened by hand, not with a wrench.

Product details

SuperPro SP0121108020 is a two inch split nut supplied with its screws, sold as a heater repair part.

Why a split nut

Union nuts crack. On a heater that has been overtightened, or on old plastic that has spent years in the sun, the nut is usually the first thing to give. A standard replacement nut has to slide over the end of the pipe, which on an installed heater often means cutting the plumbing apart to get it on. A split nut is made in two halves instead: it closes around the pipe where it sits and the supplied screws pull it together.

Fitting

Clean the pipe and the union o-ring seat before the nut goes on, then draw the halves together evenly with the screws. Tighten the union itself by hand once the nut is assembled. Unions seal on the o-ring, and reaching for a wrench is what breaks the next one.

Questions and answers

What people ask about this product, answered by our pool techs.

What is a split nut for?
It replaces a broken union nut without cutting the pipe. The nut is made in two halves that wrap around the plumbing and are drawn together with the supplied screws.
What size is it?
Two inch.
Do the screws come with it?
Yes. The screws that join the two halves are included.
How tight should the union be?
Hand tight. A union seals on its o-ring, and putting a wrench on the nut is the usual way people crack the next one.
